Question

How far away is a storm if you hear the sound of thunder 7.0 s after the lightning flash on a day when the air temperature is 31°C?

Answer 1

The speed of sound is given by:

`v=331\sqrt[]{1+(T)/(273)}`

then in this case the speed is:

`v=331\sqrt[]{1+(31)/(273)}=349.29`

The distance is given by:

`d=vt`

plugging the values given we have:

`\begin{gathered} d=(349.29)(7) \\ d=2445.03 \end{gathered}`

Therefore the storm is 2445.03 meters away
